Yang-Mills kinematic algebra via homotopy transfer from a worldline operator algebra

Roberto Bonezzi, Christoph Chiaffrino, Olaf Hohm +1

The homotopy Lie or $L_{\infty}$ algebra encoding Yang-Mills theory is the tensor product of a color Lie algebra with the kinematic $C_{\infty}$ algebra. We derive this $C_{\infty}…

The Double Copy of Maximal Supersymmetry in $D = 10$

Roberto Bonezzi, Giuseppe Casale, Olaf Hohm

We continue the program of using homotopy algebras to obtain off-shell, local and gauge redundant derivations of the double copy relations between gauge theory and gravity. We appl…

The Double Copy of Maximal Supersymmetry in $D = 4$

Roberto Bonezzi, Giuseppe Casale, Olaf Hohm

We realize off-shell, local and gauge invariant $N = 8$ supergravity in $D = 4$ , to cubic order in fields, as the double copy of $N = 4$ super Yang-Mills theory (SYM). Employing the homo…
